Advantage
1. Excellent insulation performance. This type of transformer uses transformer oil as the insulation medium, and its breakdown field strength is much higher than that of air medium. It can stably output high voltage during the test process and perfectly adapt to the withstand voltage performance testing of medium and high voltage equipment (such as power cables, high voltage switches, etc.), effectively ensuring the accuracy of test data.
2. Outstanding heat dissipation efficiency. By relying on the oil circulation heat dissipation mechanism, the heat generated during the operation of the equipment can be carried away in a timely manner. Even in long-term continuous pressure testing scenarios, it can maintain a stable working state and avoid testing interruptions or equipment losses caused by overheating.
3. Widely applicable. Through the independent operation of a single unit or the combination of multiple series and parallel units, oil immersed test transformers can achieve flexible coverage of voltage levels ranging from several kV to several thousand kV and capacities ranging from several kVA to several hundred kVA. They can meet the diverse withstand voltage testing needs of different industries and specifications of electrical equipment, and have strong adaptability.
4. It combines durability and safety. Adopting a sealed fuel tank design can effectively isolate external moisture and dust, reduce equipment maintenance frequency and cost; At the same time, transformer oil has good arc extinguishing performance, combined with the explosion-proof structural design of the equipment itself, which can significantly reduce safety risks during the testing process and ensure the safety of operators and the testing environment.
Main application scenarios
Power system: AC withstand voltage test for circuit breakers, isolating switches, and current transformers.
Cable testing: Conduct a boost pre-test on high-voltage power cables before DC withstand voltage or series resonance (note that oil transformers are usually not suitable for variable frequency series resonance, mainly used for excitation transformers with power frequency or series resonance).
Insulation material testing: Conduct breakdown strength tests on insulation boards, insulation paints, silicone rubber, etc. in the laboratory.
